Thisinvention pertains to beds, and more particularly to improvements in portable casters turn easily in anydirection and the olding beds of the roll-away? type.

One of the objects of this invention is to provide an improvedbedof the folding type,

which, when extended, will have the appearance of an ordinary bed. I

Anotherobject of this invention is to provide such a bed which, when extended,- will be securely locked in extended position.

Another object is to provide a folding bed of the type specified which will be secure against accidental collapse of the head frame upon the bed.

Another object is to provide such a bed which may be easily rolled, when in collapsed position, through narrow passages and into cramped spaces.

Another object is to provide improved means for supporting the bedding when the bed is folded up. r

Further objects will appear from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a perspective view,'illustrating a bed embodying this invention in folded position;

Figure 2 is a view of the same in extended position; Figure 3 is a detail of the latching device;

and V a Figure & is a detail of the bedding clamp. Referring to the drawings, 1 designates a head frame,which may be of any usual con- Securely atstruction, preferably of'metal. V tached to the lower part of the head'frame 1 is a sub-frame 2 extending forwardly from the head frame. This assembled combination is mounted on casters 8, so as to provide a portable bed of the so-called roll-away t pe.

This type of bed is intended to roll easily on its casters when in folded position. It

' has been found that when four casters are 10- catedat the four corners of a rectangle, there is a tendency for each pair of casters to set in casters are off-set inwardly with respect to the rear pair. When so placed, all the alined with the standards of the head and foot frames, and the sub-frame 2 is practical- By this arrangement, when the bed is extended and madeup, the side rails of the bed frame are ly hidden, so that the bed has the appearance of an ordinary straight bed.

.Pivoted on brackets 7 on the side bars of the bed'frame 6 are links 8 and 9. The opposite endsof these links are pivoted at 10 and 11, respectively, to a foot frame 12. Pivoted at 13 to each link Sis a link 14, whose other end is pivoted at 15 to the forward part of the subframe2.

By this arrangement, the bed may be folded upby raising the foot frame 12, which causes the bed frame 6 to pivot at 5 on thesubframe. During the upward n1ovement,the links" 9 are drawn downwardly by the links 14;, so as to draw the foot frame 12 downwardly. By the time the bed frame 6 has have moved to a position along the side bars,

and the foot frame 12 is also folded against the bottom of the bed frame 6. A series of springs 16 connecting the rear end of the bed frameb with the forward extending, portions of the sub-franie 2 counterbalance the weight of the bed and assist in raising the same. A weight25 counter-balances the weightof the bed. during the folding movement. In the folded position, the links 9 and 1 1 form a toggle which locks the bed in folded position. The bed cannot be lowered by pulling forwardly on the bed frame, while a light pull on thefcotfranie will break the toggle and permit the bed to be lowered.

Mounted at the foot end of the bed frame tended aosition the do 17 cn 'ae'cs the no 7 c t: a 1

per beveled face of the latch 19, moving the same back so that, when the final posit on is reached, the latch will snap into locking gagement with the dog to secure the bed in extended position.

In orderto support the bedding when the bed is raised to folded position, a pair of bedding clamps is mounted at the foot of the set. frame 6. One of these clamps is shown in detail in Figure a and comprises an arm 3 pivoted at 31 on the bed frame 6.

na th u per end of the arm is mounted a finger 3 having a curled end 33 adapted to engage bedding. The finger 32 is pivotally mounted in a tubular bearing 3 1- on the end of the arm 30. The finger is free to rotate in hearing 34, except as limited by the offset nortion 85 of the finger. This rra mits the finger to be turned in its be? -in 3 l, so as to be disengaged from the bed ii p ,n be out of the way during the normal use of tne bed. hen it is desired to clamp the beddi the finger is turned to the position illustrated in Figure 4-, its further rotation being prevented by the ofi-set portion 85. The arm is then swung downwardly to the left (Fig. l) on its pivot 31, so as to bring the finger 32 down upon the bedding to clamp the same.

' The arm 30 is held in clamping position b I a pawl 86, which engages in the teeth or a straight ratchet 37 mounted on the bed frame.

6. These bedding clamp are not a part of the present invent-ion, but are described in Patent No. 1,624,222.

Pivoted at 38 at the head of the frame 6 is a bedding holder 39. This is arranged to rest in upright position as shown in Figure 2, when the bed is extended. When the bed is folded, however, the holder 89 comes into engagementwith the rear cross-bar of the sub-frame 2, as illustrated in Figure 1. This action moves the holder 89 upwardly so as to bring the same into supporting engages ment with the bedding at the end thereof so as to assist in supporting the same. This arrangement prevents the bedding from sag: ging below the end of the bed frame, 'soas to come into contact with the .subframe or to. drag on the floor. The bedding clamps 30 at he foot of the bed securely hold the bedding to the bed frame, and the holder 39 reduces any tendency of the bedding to sag below the lower end of the bed frame. Thus, the bedding is protected against accidental soiling.

When the bed is extended and latched, the forward part of the sub-frame is tied tothe 7 foot of the bed frame through the links 14:,

9, 8, the foot frame 12 and the latch 19. Accordingly, accidental collapse ofv the bedby a folding bed of the roll-away type, which,

when extended, has the appearance of an ordinary bed. The arrangement of the pivots s with the braclrets'd inside the frame 6, renders the sub-frame inconspicuous, so as to be easily hidden when the bed is made up. The latches 19 secure the bed in extended position, so as to prevent its folding up accidentally. These latches are manually disena 'ed when the bed is to be folded u 9. .D 23

1Vl1iie this bed has been described as a unitary structure, it is ob-vlous that certain features may be'used to advantage without others, and the useofsuch sub-combinations is cont mplated by this invention.

It is rurther obvious that various changes may be made, within the scope of the appended claims, in the details of construction, without departing from the spirit of this invention. it is, therefore, to be understood t: at this invention is not to be limited to the 7 lie details shown and described.

i laving thus described the invention, what YVILLI'AM J. DUVALL.
